The problem is when I compile the program it does not read the up arrow key. When I press it, it sits there.


CODE
#include <iostream>
#include <ctime>
#include <conio.h>
#include <string>
#include <windows.h>
#include <winuser.h>
using namespace std;
int main()
{
int user;    

cin >> user;


if(user == WM_KEYUP)
{
     cout << "You pressed the up key" << endl;
}
    
  

    return 0;
}

Well that is REALLY not how to use WM_KEYUP... cin reads in standard characters and will do nothing for special keys (Fn keys, ALT, CTRL, etc).

So, how do you detect arrow keys.

One solution is to use the conio.h -- not the best solution but it is often simple and. Since you seem to be on windows than using the window API is the natural solution.

see this old post for more info (sorry I don't have time to write a specific example and I have answered this question before).
